What is IPv4 Forwarding?

IPv4 forwarding is a network feature that allows a system to route network traffic between different network interfaces. When enabled, it ensures proper communication between various Seclore components and services.


Why is IPv4 Forwarding Required?


Impact on Policy Server

  • Network Connectivity: Prevents network adapter connection failures and other communication-related exceptions.
  • Database Operations: Ensures stable database connections and prevents connection timeouts


Impact on Seclore Online Components

  • Essential for Communication: IPv4 forwarding is required for proper communication between Seclore Online (SO) components, including Lite Viewer (LV), Document Server (DS), and other SO services
  • Database Connectivity: Ensures reliable database connections for all Seclore Online components



How to Check IPv4 Forwarding Status

Use the following command to check the current status:

sysctl net.ipv4.ip_forward
Plaintext

Result Interpretation:

  • 0 = Disabled (requires action)
  • 1 = Enabled (correct configuration)

Resolution Steps

Enable IPv4 Forwarding

  1. Contact your Linux system administrator.
  2. Request them to enable IPv4 forwarding on all Seclore servers.
  3. Use the command: sysctl net.ipv4.ip_forward=1 to enable it.
  4. Restart the services after this change.
